Product Introduction

Overview

The SN74CBTD3861DWR is a 10-bit FET bus switch with level shifting, manufactured by Texas Instruments. This component is designed to provide high-speed TTL-compatible bus switching, making it suitable for applications requiring fast edge rates and high-frequency operations. The device features a single output-enable (OE) input, allowing for the connection or disconnection of the two ports (A and B) based on the OE state. When OE is low, the switch is on, connecting port A to port B, and when OE is high, the switch is open, resulting in a high-impedance state between the two ports.

Key Features

  • Level Shifting: The device includes a diode to VCC, enabling level shifting from 5-V signals at the inputs to 3.3-V signals at the outputs.
  • Low On-State Resistance: The switch has a low on-state resistance of 5 Ω, allowing connections with minimal propagation delay.
  • TTL-Compatible Input Levels: The device is designed to work with TTL-compatible input levels.
  • Single Output-Enable (OE) Input: The OE input controls the connection or disconnection of the two ports (A and B).
  • High-Speed Operation: Suitable for applications with fast edge rates and high frequencies.

Applications

  • Bus Switching in High-Speed Systems: Ideal for systems requiring fast data transfer and minimal propagation delay.
  • Level Shifting Applications: Useful in scenarios where voltage level translation between different logic levels is necessary.
  • High-Frequency Operations: Suitable for applications operating at high frequencies, such as in telecommunications and networking equipment.
  • General-Purpose Logic Circuits: Can be used in various general-purpose logic circuits where bus switching and level shifting are required.
